Coscoroba swan / Cisne Coscoroba (Coscoroba coscoroba)

The Coscoroba Swan breeds in South America from southern Chile and central Argentina south to Tierra del Fuego and the Falkland Islands. In winter it flies north to central Chile, northern Argentina, Uruguay and the south east tip of Brazil. The habitat is well-vegetated swamps and lagoons, where it lives mainly on grasses and small water plants, but also mussels and fish. The population is estimated as 100,000 birds, hence it is regarded as an endangered species. The female incubates the eggs, while the male stands guard and aggressively helps to protect the fledglings against predators after hatching. It lives to an age of approximately twenty years.
